Application filed May '28,

To aZZwhom itmag concern:

Be it known that W6, JOHN B. SWAN, JOHN A, Rooms, and GLENN V. JACKSON, citizens of the United States, residin at Gladstone, in the county of Deltaand tate of Michigan, have invented certain new and useful Improvements in Bedspring Appara tus, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a bed-spring apparatus, and the object of the invention is the construction of a comparatively simple and efficient bed-spring apparatus which will permit the adjustment of the tensionof the mattress-supporting device to accommodate different loads, and which apparatus will give the maximum amount of use.

l/Vith this and other objects in view, our invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims. 7 v

In the drawings: 1 Figure 1 is a top plan view of the appara tus constructed in accordancelwith the present invention, while Figure 2 is a view, taken on line 2-2, Fig. 3, and looking in the direction of the arrows. 1

Figure 3 is a view, in side elevation, of. the apparatus. v Figure 4 is a fragmentary, plan view of' v another embodiment of the apparatus.

Figure 0 is a view similar to Fig. 2, but showing another embodiment of the adjusting and tightening device.

Figure 6 is a fragmentary, perspective view of the apparatus showing part of the main frame, and one of the legs thereon.

Figure 7 is a fragmentary, perspective. view of the embodiment shown in Fig. at.

Figure 8 is a fragmentary, perspective view of the embodiment shown in Fig. 4L, showing particularly the connectionof the single cables and the tie wires of the mattress-supporting device of the apparatus.

Referring to the drawings by numerals, 1 designates the main frame, which comprises the side sectional tubes 2 connected by turn buckles 3; the end tubes 4: are connected to the sectional side, tubes 2 by elbows 5. t

On the end tubes 4: of the main frame 1 by adj usting Specification of Lette Patent. 2 Pgybggnt gfl Aug,

1e91, Serial No. 473,222.

are end frames 6; each end frame 6 -comprises a top plate .7, a bottom plate S- and a plurality of U-shaped yokes'9;'lthe U shaped yokes 9 are interposed between the top and bottom plates? -'-and 8, respectively,

and are fastened by rivets 10 thereto. These yokes have an outwardly-bulged body ,por-

tion 11 that fits upon the end tubes 4 of the r main-frame 1.

The mattress-supporting 'device12 (Fig;

3) includes coil springs 12 and cable 13; a

the outer ends of coil sprin s 12Iare secured in apertures 14 formed in the top; plates 7, and the cable 13=is threaded through the loops 15 formed on the inner endsfiof springs 12.

The adjusting and tightening device :16:

comprises a plurality of springs 17 connected at their outer ends, at 18, to the bot tom plates 8, and their inner ends are fastened to disc plates 19. The disc plates19,

are pivotally mounted, atv 20, in the bifurcated outer ends of threaded bolts 21. These bolts 21 are threaded onto turn buckle22, so that by adjusting turn buckle 22, the

tension of springs 17 will be controlled, and i I as the end frames 6 have a 'slight swingr ing or rotary movement upon'the endsof the main frame, the tension of the mattress supporting device 12 can be controlled. The;

tension of springs 12 can also be controlled frame. We preferably place legs 23 on the main the turn buckles 8 of the main i frame near each corner-so that these legs will rest upon the side rails of the bedstead (not shown). Each leg 23 comprisesan outwardly-curved'base 24, Fig. 6, and vertical body 25; The body is fastenedb y rivet 26 to the outerv face oftlie collar 27 under the shoulder 28; the rivet 26 extends through the body1 25, collair27 and the sidetubes 2;" the placing of a top edge of the body 25 against the under face of the shoulder 28,

together with'the positioning of the rivet.

in the leg, collar and main frame, produces a very permanent and durable connection. In the embodiment shownin Fig. 5, instead of using the coil springs 17, we use cables 17 otherwise, the embodiment shown in Fig. 5 is the same as that shown in 2, the difference being in the specific const ruc-: tion of the tightening devices 16 and 16 (Figs. 2 and '5). In the embodiment shown in Figs. 4, 7 and 8, eye-bolts 29 are fastened by nuts 30 disprings 12, and tie wires 33 extend trans versely of the apparatus and are looped. around, at 34, the cables 32. The ends of the cables 39 (Fig. i) are fastened to the inner ends of springs 12 by clips 35 by adjusting the turn buckles 3 of the main frame, and the turn buckle 22 of the tightening device, the mattress-supporting device 36, shown 1n Fig. 4:, can be tightened or loosened, at the will of the operator.

It will beunderstood that our apparatus furnishes a rigid bed-spring with lightfr'aine work, which is made so as to permit suitable adjustment that allows the struc ture to be shortened or extended, thus relaxing or tightening the. springs to suit the needs of the individual and to take up the lost tension of coil springs as they grow older in use.

Vdhile we have described the preferred embodiments of our invention, and have illustrated the same. in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and we, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.

What we claim is:

1. In an apparatus of the class described, the combination of a main frame, end frames positioned around portions of the main frame, each end frame comprising trans versely extending top and bottom plates, yokes connected to said top and bottom plates and extending around portions of the main frame, and mattress-supporting and tightening devices connected to said plates of the end frames.

2. In an apparatus of the class described,

the combination of a main frame, end frames extending over port-ions of the main frame, and mattress-supporting and tightening devices connected to said plates of the end frames.

3. In an apparatus of the class described, the combination of a main frame, end frames supported by said main frame, each end frame comprising a top and a bottom transversely positioned plate, a plurality of U- shaped yokes over portions of the main frame and positioned between said plates, fastening means securing the yokes and plates to gether, each yoke provided with an outwardly-bulged body portion upon the main frame, a yieldably mattress-supporting device connected to the top plates, and an ad justing and tightening device connected to the lower plates of the end frames.

at. In an apparatus of the class described, the combination of a main frame, end frames supported by said main frame, each end frame comprising top and bottom transversely extending plates, a plurality of yokes over portions of the main frame and posi tioncd between said plates, fastening means securing the yokes and plates together,each yoke provided with an outwardly-bulged body portion upon the main frame, a yieldable mattress supporting device connected to the top plates, and an adjustable tightening device connected to the lowerplates of the end frames, as and for the purposes set forth.

5. In an apparatus of the class described, the combination of a main frame, a plurality of yokes over portions of the main frame, each yoke provided with an outwardlybulged body portion upon the main frame, a yieldable mattress supporting device, means connecting the mattress supporting device to the upper portions of said yolzes, an adjustable tightening device, and means connecting said adjustable tightening device to the lower portions of said yokes, as and for the purposes set forth.

In testimony whereof we hereunto affix our signatures.
